It's the 3-line xfer sw. Says that 'control voltage' is 220 VAC but the conn drawing provided with the unit (and in the figures above on the desertcart sales page) shows it wired for 110V operation. That is one side of the line goes to AR or BR, that's OK but the the AN and BN wires are tied to neutral, that is the center tap on the xfmr out on the pole. For 220V operation it should go to the other line, the other side of the xfmr not to the neutral line. I opened the unit up and applied 110VAC thru a diode bridge directly to either of the actuating coils inside (they main actuating coils want at least full-wave rectified AC) and it would reliably snap back and forth at 110VAC tho not as vigorously as at 220VAC. I note that there is a 220VAC (NNC68BP-4Z) coil relay in there wired to give the A connection preferential control over connecting its side to the load. This relay will not pull in on 110VAC so that's what makes it a 220VAC control unit. I'm saying the unit is indeed a 220VAC control unit, 220VAC is required to operate the unit, but the wiring diagram provided with the 220vac unit (and the diagrams on the sales page) shows it wired to operate from 110VAC. JOTTA must fix this diagram to show correct connection. It's confusing everyone who buys it! It's an excellent design, very safe, very fast, very reliable. Everyone who wants an ATS should get it. But JOTTA needs to fix their documentation! Correct me if I'm wrong. Review: Works well to turn generator automatically! - Sent this Jotta cable station, along with a portable electric generator to my uncle in Cuba. They only get like 3 hrs a day of electricity. This combo has allowed him to run the generator on auto, & has changed his life.

They only get like 3 hrs a day of electricity. This combo has allowed him to run the generator on auto, & has changed his life. Highly recommend! ### ⭐⭐⭐⭐ Failed after less than a day but failure due to using inverter output. *by S***Y on June 22, 2023* I installed this on Sunday. I was so happy that it worked flawlessly. When primary power failed, load was transferred to the backup power without a break in the supply. When primary power was switched back, the load was transferred seamlessly to the primary source. Then on Monday evening I noticed that the enrgized light on the backup side (green light) was not on. I thought the secondary power was off. But a check with the meter showed that there was secondary power. I then shifted to manual mode and switched source to secondary and power was still being delivered to the load. This showed that connections were good and backup power was good. Meaning the energizer circuit has conked off!! AT US $ 40 would expect a much more robust and long lasting device. I am updating this review because the mistake was mine. It's not meant to use inverter output as one of the inputs. It does state that in the description but since my inverter was a true sine wave inverter, I thought that would still work. I had written directly to the seller and they were extremely quick in their responses. After a few exchanges they quickly identified the cause of the failure and assured me of a full refund. The product does what its designed to do and has an extremely good transfer time. However, its not meant for inverter output. ## Frequently Bought Together - Jotta W2R-2P/3P/4P 100A 220V Mini ATS Automatic Transfer Switch 100 amp Electrical Selector Switches Dual Power Switch (4P 100A 220V) - Chtaixi AC Miniature Circuit Breaker, 50 Amp 120V/240V 2 Pole DIN Rail Mount Circuit Breaker, Thermal Magnetic Trip, Solar AC Disconnect Switch MCB C50 - MOLLOM 8 Way Circuit Breaker MCB Distribution Protection Box with DIN Rail, IP65 Waterproof,for Indoor and Outdoor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.eg/products/211841746-dual-power-automatic-transfer-switch-2p-100a-110v-pc-type](https://www.desertcart.com.eg/products/211841746-dual-power-automatic-transfer-switch-2p-100a-110v-pc-type) --- *Product available on Desertcart Egypt* *Store origin: EG* *Last updated: 2026-05-09*
